SPECIFICATION forming part of Letters Patent No. 307,958, dated November 11, 1884.

Application filed July 12, 1984. (No model.)

I 0 to whom, it may concern.-

Be it known that I, JAMES KINNEY, a citizen of the United States, residing at Cumberland, in the county of Barron and State of WVisconsin, have invented certain new and useful Improvements in Sleighs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the .art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked there on,which form a part of this specification.

Figure 1 of the drawings is a vertical crosssectional view of my device. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is an end view of the part B, and Fig. at is a side view of the same. Fig 5 is a plan View of part B, and Fig. 6 is a bottom view of part A.

This invention has relation to that class of road-sleds in which each runner is designed to have some freedom of movement independently in the direction of the draft; and it consists in the construction and novel arrangement of devices, as hereinafter set forth, and

pointed out in the appended claims.

.In the accompanying drawings, the letter A designates the upper casting, which is designed to be secured to the transverse bar of the sled, and B the lower casting, to which the runner is rigidly fastened. The upper casting, A, consists vof the flanged head 0 and the short leg D, which extends downward from the head. The bottom of the leg 0 is hollowed out to form a hemispherical socket or cavity, E, in the sides of which, near the margin, are the opposite inwardly-projecting bearings F. These bearings are concave on their inner faces and merge into the margin G at their lower ends. Their upper portions terminate in shallow convex; shoulders H. Above these shoulders the full spherical curvature of the socket is preserved. The lower casting, 13, consists of the longitudinal plate K and the hemispherical boss L, which is formed on the middle portion of said plate, allowing on each side a flange-bearing, lVI, adapted to engage the marginGof the socket leg of the upper casting when the boss is The margin G or botseatcd in the socket.

top of the socket.

tom edge of the socket is slightly convex from front to rear, so that a certain amount of rocking action is permitted to the runner. The upper portion, N, of the boss L has its surface fully curved, this portion, however, terminating at each end in a broad and shallow depression, P, and at each side in a shoulderbearing, S, below which is a lateral recess-way, V, which communicates with the depression P. -\Vhile each of these depressions communicates with a recess-way on one side,it is cut off from the recess-way on the opposite side by a stop or guard, Z, which is a rise or continuation downward of the upper spherical portion, N, of the boss. \Vhenthe runner carrying the casting B is to' be secured to the leg-casting A, it is turned so that the lateral bearings of the socket will enter by the depressions P the recess-ways of the boss, the upper portion of the boss ascending into the The runner being then turned into correct position,the shoulder-bearings S of the boss will engage the lateral inner bearings, F, of the socket, and the castings will be connected in a secure manner, but such as will allow each runner a certain amount of rocking movement as well as a horizontal turning motion. In this manner a connection is provided which will allow each runner to be moved forward independently of theother in starting a load. In order, however, that the pivotal motion between the'runner-casting and the socket shall not be too great, the stops Z are provided. These steps are arranged in reverse relation on the bosses of the opposite runners, so that each runner can advance but a certain distance ahead of the other.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s 7 1. A sled-leg casting having a socket inits lower end formed with internal lateral bearings and with a convex margin, substantially as specified.

2. The runner attachment for sleds, consisting of the runner-plate B, having the boss formed with end depressions, I, lateral shoulders S, and recess-ways V, and the leg A, having the head .Gand the socket E, formed with interior lateral proj ectingbearings,F, substantially as specified.

3. The runner attachment for sleds, consisting of the detachable interlocking boss, and socket-castings having stops to prevent extra pivotal action, substantially as specified. I

4. Arunner attachment for sleds, consisting l of a leg-casting having in its bottom a socket I formed with a convex margin, and a runnen- I casting having an interlocking boss adapted to I engage bearings of the socket, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES KINNEY.
